(correlates) that are associated with PA in older adults is needed.
The aim of this study was to identify how demographics and
physical activity history, environmental- and biological correlates
are associated with objectively measured PA in older adults.
Methods:
PA was assessed objectively in 850 older adults
(70–77 years, 405 females) using the Actigraph GT3X+ activity
monitor. Demographics (gender, age, education) and activity history
(PA at 40 years), environmental correlates (i.e. social support
and neighborhood) and heart disease were self-reported, while
cardiorespiratory fitness (CRF) and BMI were directly measured.
Hierarchical multivariable regression analysis was used to identify
important PA correlates.
Results:
The complete set of correlates explained 27.0% of the
variance in overall PA level in older adults. CRF, gender and season
were the most important correlates, explaining 10.1%, 3.9% and 2.7%
of the variance, respectively. Females were more physically active
than males and PA declined with age for both genders. Furthermore,
education was positively associated with PA for males, not for
females.
Conclusions:
This is the largest correlates study combining
objectively measured PA and directly measured CRF in older adults.
Our findings provide new knowledge of how different correlates are
associated with overall PA. The main finding was that CRF, measured
as VO2peak, was the correlate with the strongest association to
overall PA.

Objectives:
Accelerometers are commonly used to assess physical
activity (PA) on a population sample. To assess the proportion of the
sample meeting PA recommendation, data are analyzed using an
absolute intensity-cut-point for moderate-to-vigorous PA (MVPA),
regardless of gender and cardiorespiratory fitness (CRF). However,
as CRF normally declines with age, older-adults are often unable to
reach MVPA defined in absolute terms. To enlighten this problem
this study present MVPA using both relative and absolute intensity-
cut-points on the same sample of older-adults. The secondary aim
was to present a comprehensive description of PA in an elderly
Norwegian population.
Methods:
PA was assessed using the Actigraph GT3X+
accelerometer in 1179 older-adults (606 females) age 70–77. CRF
was directly measured as VO2peak. The absolute MVPA cut-point
selected was 2691 triaxial counts-per-minute (CPM). The relative
MVPA cut-point was based on categorized VO2peak (low-medium-
high) and gender, and ranged from 669 to 3048 triaxial CPM.
Results:
Forty and seventy percent met the PA recommendations
when absolute and relative MVPA cut-points were applied to the
same population sample of older-adults, respectively. Females spent
significantly more time in higher relative intensities, compared
to males. Overall PA declined with age, while minutes in higher
intensities were stable. Moderately and highly fit individuals were
more physically active, while the unfit spent more time in the
higher relative intensities.
Conclusions:
This is the first study comparing absolute and relative
cut-points in older adults illustrating how PA surveillance based on
absolute intensity MVPA could underestimate PA in those with low
CRF.

Objectives:
The chronic immune competent HIV-1 infected
population are at increased risk of cardiovascular disease (CVD),
whether chronic inflammation contributes to the premature
development of CVD is yet to be established. Arterial stiffness is
an independent sub-clinical marker of CVD and directly correlates
with age.
Methods:
74 HIV positive males on antiretroviral treatment, with
undetectable viral loads, were recruited and grouped according
to their cardiovascular risk (Framingham score). They underwent
assessment of arterial stiffness, as measured by carotid femoral
pulse wave velocity (CFPWV). A one way ANOVA was performed
to determine the difference in CFPWV in each group. Multiple
regression was performed to consider further predictors of CFPWV.
Results:
A one-way ANOVA demonstrated a linear trend,
F(2,31) = 11.46, p
<
0.001,
w
= 0.4, between CFPWV and Framingham
risk group. Multilinear regression, with CFPWV as a dependent
variable and classical cardiovascular risk factors as predictors,
demonstrated that age (b = 0.06, p
<
0.01), diabetes (b = 2.37, p
<
0.01)
and systolic blood pressure (b = 0.04, p
<
0.01) were significant
predictors of CFPWV. A second regression, with HIV related factors;
years with HIV (b = 0.01, p = 0.72), years on anti-retrovirals (b = 0.01,
p = 0.86), nadir CD4 (b = 0.001, p = 0.63) provided no additional
predictive power to the model.
Conclusion:
In this HIV-positive cohort, CFPWV is positively
associated with Framingham score. The differences between the
low and high risk cardiovascular groups, appears to be due to
traditional cardiovascular risk factors, with HIV related factors
adding no predictive power to the model.

Objectives:
In some countries oral health status (OHS) is
still underestimated by national healthcare systems (NHS).
Low reimbursement of oral healthcare (OHC) may cause OHS
asymmetries between different social classes. Socio-economically
disadvantaged elderly may be most affected. Our aim was to
evaluate the impact of social determinants in OHS among patients
≥75 years admitted in a medical ward.
Methods:
Cross-sectional study during 1 day. Comprehensive
geriatric assessment, dental examination.
Results:
100 patients were included, average age 83.7 years, 63%
males, 62% widowed, 25% nursing home residents (NHR), average
Cumulative Illness Rating Scale Geriatrics 11.2, average Barthel 62.6.
Prevalence of cognitive impairment and malnutrition were 31% and
70%. Average number of teeth (ATn) was 6.7
±
8.4, 36% used oral
prosthesis. Prevalence of total edentulism, caries and periodontal
disease were 46%, 24% and 21%. In patients with higher education
professions there was a higher ATn (Graffar 1/2 9 vs Graffar 3/4 7.5
vs Graffar 5 5.9, ns), a lower prevalence of caries (Graffar 1/2 16.6%
vs Graffar 3 22.2% vs Graffar 4/5 23.5%, ns) and usage of dental
prosthesis (Graffar 1st 0 vs 3rd 5.6% vs 5th 61%, ns). ATn was
lower in analphabets (4.88 vs 7.36) and widowed (p 0.04), and
higher among community-dwelling patients (7.6 vs NHR 4.1, p 0.08).
